The Real Difference
Both offer free tiers, so the real question is what you get when you start paying.
Grammarly stands out with Real-time grammar, spelling, and punctuation corrections and Tone detection and rewrite suggestions. QuillBot counters with Paraphrasing in 9 modes and Summarizer tool.
Grammarly's Achilles heel: suggestions can be overly conservative and strip personality from your writing if you accept everything blindly. QuillBot's: paraphrasing can produce awkward phrasing — and the free tier’s 125-word limit is almost unusable. Pick whichever weakness you can live with.
Bottom Line
If you value real-time grammar, spelling, and punctuation corrections and anyone who writes emails,, go with Grammarly. If students and academics who matters more, QuillBot is your pick. Neither is a bad choice — but one will fit your workflow better.
